Abstract: PURPOSE: To accomplish a rational formation of a dehydration groove by means of protrusions provided in such a manner as to form drain guide grooves inside the body of a cylindrical dehydration tank with a closed bottom made of a synthetic resin.  
     CONSTITUTION: A number of T-shaped protrusions 3 with a rib on either side thereof is formed on the inner wall of a cylindrical dehydration tank 1 with a closed bottom made of a synthetic resin in such a manner as to extend vertically from the bottom thereof. Thus, slim U-grooves 4 and 5 equivalent to a guide groove are formed. In operation, when the tank 1 rotates at a high speed together with washing, all water dehydrated from the washings is allowed to flow into the grooves 4 and 5 and go up therealong rapidly. Consequently, the water is discharged out of the tank 1 through upper through holes 6. With such an arrangement, an effective dehydration can be performed without many dehydration holes. Accordingly, the dehydration tank can be formed with ease, while improving the strength thereof.
